Big booty? No booty? Curvy? Flat? Every girl, and every body, is different — and that includes you and yours! Your personality, everyday activities and just the way you feel about things (at any given moment!) all shape your decisions about what clothes you like to wear, from top to bottom.

Although it’s easy to dismiss undies as just a garment you slip on before choosing your outfit, the best pair — best for you, that is — is more revealing of your personality than you’d think. Undies come in a wide range of cuts and styles, each with its own pros and cons. Which one is right for you?

If you’re feeling undie-whelmed by all the options, Aerie is here to help! Use this guide to help you personalize your search for undies. Take our fun quiz, then read more about the undies that fit you best!

Thong: Nothin’ but cheek! This is the most revealing style available and is great for fashion-forward girls who love body-con dresses and skinny jeans — but not panty lines. Super-soft stretch cotton and a low rise make our thongs extra comfy, even if you haven’t tried this style before.

Cheeky: If you’re not ready to go full cheek but are looking for less coverage than a bikini, cheekies are a great compromise. These undies offer just a peek of cheek, giving you a hint of sass. (Want to go a little further? The mini cheeky shows even more cheek while still offering more coverage than a thong.)

Bikini: Are you a classic kind of girl? The bikini will never go out of style, and for good reason — it provides a comfortable amount of backside coverage without sacrificing any cuteness. In a wide range of pretty prints and lace trims, this is a great choice for the girl who values a practical wardrobe but still wants a sprinkle of flirty, feminine style.

Boyshort: Looking for a pair of undies that can do double duty? Boyshorts offer a low rise but no cheek peek, and keep you covered from a flippy skirt on a windy day to lounging around the house and catching some zzz’s. All you need is a pair of boyshorts and some knee socks for an insta-lounge session after work or school. Underwear for loungewear. How easy is that?

Girly Short: If you’re a boho kind of girl, make your underpinnings match your free spirit by choosing the Girly Short style. These ultra-romantic undies have all the coverage of a boyshort but are made entirely of feminine lace.

Boybrief: So you’re wanting a little more than a bikini but not quite feeling the boy or girly short? The boybrief is a great option, serving up just the right amount of backside coverage. It’s a great choice for the sporty girl who has no time to worry about wedgies! And for those who want to fine-tune things just a teeny bit more, consider the Mini Boybrief, which keeps your curves in place but allows just a hint of cheek to peek.

100 million cheeks can’t be wrong! Aerie’s #1 selling undie fit, the Boybrief, now has a new – and cheekier – BFF! Even if a thong is your go-to fit, every girl needs a full coverage undie in her drawer. Our Mini Boybrief is perfect for the girl who likes fuller coverage but still wants just a peek of cheek!
